Installation of docker compose without using pip fails

[NateV]

Hi,
Nice work here. I was trying to install docker-compose the way you do here (and the way Docker recommends) with curl. But I kept running into errors about the compose module not being available, which I finally solved by installing docker-compose with pip.

How'd you avoid that problem?

Thanks!

Hi,

What OS / version are you using? What was the state of the system before you installed Docker / Compose?

I never experienced that issue. Just using this role should be good enough to get up and running with no additional installation steps.

Hmm. I'm using ubuntu xenial. Its possible there's conflicting python modules. I imagine your playbook assumes a machine that didn't have docker-py or docker python modules installed with pip. My machine is a little messy. The pip install approach has worked now, and its probably best for me just be happy with that, rather than trying to keep digging at this. Thanks!

My playbook consists of bootstrapping a machine to run Ansible, doing a few other system related things, installing Docker / Docker Compose with this role and then running my Dockerized applications.

I have never installed docker-py.

You might want to run which docker-compose to see if it's using the curl version or your pip version.
